Octopath Traveler II looks similar to the first game at a glance, but its Steam directory adds an explicit Steam branch and current transfer reports call out SystemData.sav alongside SaveData slot files. That makes whole-folder backup more important than copying a single large slot. SaveEditor records the current Microsoft Store WGS path separately and avoids claiming that a Game Pass blob can simply be renamed into a Steam SaveData file without the system-data context.
Which storefront context matters
Documented Octopath Traveler II PC launchers/storefronts: Steam, Microsoft Store. Steam and Game Pass storage differ. Current community migration notes identify both slot-sized files and separate system data in WGS. The active storefront/account should be identified before any restore because cloud and local storage may not use the same path or container across editions.
Documented cloud behavior
Steam Cloud and Xbox Cloud are documented. Cloud synchronization is useful for continuity, but it can also turn a restore into a conflict-resolution event. Let synchronization settle before making a manual backup, and keep an offline copy outside any folder monitored by the launcher or operating-system sync service.
Local save roots still matter
The researched local save boundary is Windows: Steam: %USERPROFILE%DocumentsMy GamesOctopath_Traveler2Steam<user-id>SaveGames ; Microsoft Store: %LOCALAPPDATA%Packages39EA002F.OCTOPATHTRAVELER2_n746a19ndrrjgSystemAppDatawgs; the known file or folder pattern is SaveData*.sav plus SystemData.sav on current Steam builds.. A cloud-enabled game still has concrete local data involved in ordinary play, and that local context is what you need when identifying which copy was modified most recently.
Avoid accidental overwrite loops
Copy the whole SaveGames directory on Steam, including SystemData.sav. For Microsoft Store, preserve all WGS containers before identifying slot and system payloads. When restoring, close the game and launcher, preserve both the current local copy and the backup you want to test, then place the intended data in the matching profile/storefront location. Do not repeatedly open the game between different copies without noting which side the cloud client selected.
Compatibility and conflict checks
Do not restore only one SaveData slot if you are trying to reproduce the complete profile state. Cross-store migration may need both slot and system payload handling. If progress disappears or rolls back, If an imported slot seems blank or incomplete, check whether SystemData came from the same snapshot and whether Steam Cloud restored the previous directory. Resolve identity/path/cloud questions first. A cloud conflict is not proof that the save itself is corrupt, and a successful upload is not proof that files from another storefront are compatible.
